NVUE Switch
|
||||
===========
|
||||
|
||||
This role configures Cumulus switches using the `nvue` Ansible module. It
|
||||
provides a fairly minimal abstraction of the configuration interface provided
|
||||
by the `nvue` module, allowing for application of arbitrary switch
|
||||
configuration options.
|
||||
|
||||
Requirements
|
||||
------------
|
||||
|
||||
The switches should be configured to allow SSH access.
|
||||
|
||||
Role Variables
|
||||
--------------
|
||||
|
||||
`nvue_switch_config` is a list of NCLU commands to apply to the switch, and
|
||||
defaults to an empty list. Commands must be formatted without the `nv` prefix,
|
||||
which is added by the `nvue` module before execution on the switch.
|
||||
|
||||
`nvue_switch_interface_config` contains interface configuration. It is a dict
|
||||
mapping switch interface names to configuration dicts. Interfaces can be switch
|
||||
physical interfaces, but also special interfaces such as bridges or bonds. Each
|
||||
dict may contain the following items:
|
||||
|
||||
- `description` - a description to apply to the interface.
|
||||
- `config` - a list of per-interface configuration, each applied with a `net
|
||||
add <type> <interface-name>` prefix.
|
||||
- `type` - type of interface, e.g. `bond` or `bridge`. If this field is absent,
|
||||
the `interface` keyword is used.
|
||||
|
||||
Dependencies
|
||||
------------
|
||||
|
||||
None
|
||||
|
||||
Example Playbook
|
||||
----------------
|
||||
|
||||
The following playbook configures hosts in the `nvue-switches` group. It
|
||||
applies global configuration to configure a BGP AS and add two EBGP neighbors
|
||||
using BGP Unnumbered, enables two host interfaces with jumbo frames, and
|
||||
attaches them to a traditional bridge called `bridge1` configured with an IP
|
||||
address.
